    Update 'Introduction to Ironic' document

    The first few sections of the 'Introduction to Ironic' document were updated to:
    - mention that it is included with OpenStack releases starting with Kilo
    - mention that Swift is missing from the Conceptual Architecture diagram
    - removes Figure 1.3.1 "Deployment Architecture" and the text surrounding
      that for several reasons: it places ir-cond on the same host as n-cpu, which
      is not advisable in some situations; it suggests placing ir-api on a
      monolithic "Cloud Controller Node", but does not explain why this unusual
      choice was made; and it does not include any depiction of the physical
      servers which Ironic is going to manage, nor the IPMI network connectivity
      to them which is required.
    - mentions that for security reasons, ir-cond should be placed on an isolated
      host, as it is the *only* service which requires access to both data plane
      and IPMI control plane.
    - modified (what was Figure 1.3.2) deployment_architecture_2.png so that it
      doesn't include a figure number
